Techniques to display an input device on a mobile device

ABSTRACT

A method and system may detect an external display coupled to the mobile device. A digital input device may be presented on the integrated touch sensitive display of the mobile device to operate the mobile device. Multimedia content may be presented on the external display in response to the operation of the mobile device through the digital input device.

BACKGROUND

Mobile devices are becoming increasingly smaller over time in order tofacilitate transport, storage and convenience for a user. Along with thesmaller form factors, however, mobile devices typically implementintegrated displays with a limited amount of display area. This makes itdifficult for a user to view content presented on the smaller integrateddisplays. To solve this problem, a user may couple a mobile device to anexternal display, such as a liquid crystal display (LCD) monitor, via awired or wireless connection. The external display may have a largeramount of display area relative to the integrated display of the mobiledevice. In this configuration, content presented on the smallerintegrated display of a mobile device may be replicated to the largerexternal display to enhance viewing by a user.

Despite the larger image presented by the larger external display, thesmaller integrated display of the mobile device typically continues topresent the same view as that shown on the larger external display. Thisseems redundant given that one purpose of the larger external display isto become a primary viewing device for the mobile device. In some cases,the smaller integrated display may be turned off to conserve power tothe mobile device. In both cases, however, the smaller integrateddisplay remains an underutilized resource of the mobile device. It iswith respect to these and other limitations that the presentimprovements are needed.

DETAILED DESCRIPTION

Embodiments are generally directed to techniques for managing multipledisplay devices coupled to a mobile device. Some embodiments areparticularly directed to techniques for presenting different content oneach display device coupled to a mobile device. In one embodiment, forexample, a mobile device may detect an external display device. Themobile device may be coupled to the external display device via wired orwireless connections. The mobile device may comprise an integrated touchsensitive display. Furthermore, the mobile device may implement adisplay manager arranged to present different content on each of thedisplay devices, rather than identical content as presented byconventional solutions.

In an embodiment, for example, the mobile device may detect an externaldisplay device. In an embodiment, a display manager may present adigital input device on an integrated touch sensitive display of amobile device, while simultaneously presenting multimedia content froman application on an external display coupled to the mobile device. Inan embodiment, the digital input device presented on an integrated touchsensitive display of a mobile device may operate the mobile device. Adigital input device may comprise, for example, a software version of akeyboard, a pointing device, a touch pad, or any other type of physicalinput device. In this arrangement, the integrated touch sensitivedisplay may be used to replicate functions of a physical input device,without necessarily needing to connect any physical input devices to themobile device. In this manner, an integrated touch sensitive display fora mobile device may be utilized as a custom input device for the mobiledevice, rather than simply presenting identical content as thatpresented on an external display device. As such, an integrated touchsensitive display is converted from a wasted resource to a productiveresource of a mobile device.

In an embodiment, multimedia may be presented on the external display.In an embodiment, the multimedia may be presented in response to theoperation of the mobile device through the digital input device.

In some cases, a physical input device may be coupled to a mobiledevice. In such cases, the integrated touch sensitive display may beused to augment functions of the physical input device. For instance, aphysical pointing device such as a mouse may be coupled to a mobiledevice, and used to select content presented on an external display.However, the external display may not provide sufficient resolution orgranularity to specifically pin-point content presented on the externaldisplay. In this case, the integrated touch sensitive display mayprovide a more detailed version of an area around a pointer positionedon the external display, thereby allowing a user to select a moreprecise location within the detailed version by tapping on theintegrated touch sensitive display at the desired location. Other usescenarios exist as well.

FIG. 5 illustrates an embodiment of a first exemplary logic flow. Logicflow 500 may be representative of the operations executed by one or moreembodiments described herein. It should be noted that the methodsdescribed herein do not have to be executed in the order described, orin any particular order. Moreover, various activities described withrespect to the methods identified herein can be executed in serial orparallel fashion.

As shown in logic flow 500, an external display coupled to a mobiledevice may be detected 505. The mobile device may detect 505 that one ormore external displays are coupled via a logic device 205, shown in FIG.2. The logic device may detect that the mobile device is coupled to anexternal display via a wired connection. Examples of a wired connectioninclude, but are not limited to, cables and/or cords. In an embodiment,the logic device may detect that the mobile device is coupled to anexternal display via a wireless connection. Examples of a wirelessconnection include, but are not limited to, Wireless Fidelity (WiFi)and/or Wireless Display (WiDi). The embodiments, however, are notlimited to these examples.

Alternatively or in addition, the display manager 210, as shown in FIG.2, in the mobile device may manage 507 the multiple display devices. Inan embodiment, the mobile device may manage 507 an integrated touchsensitive display of the mobile device. In an embodiment, the mobiledevice may manage 507 one or more external displays.

In an embodiment, a digital input device may be presented 510 on theintegrated touch sensitive display of the mobile device to operate themobile device. For example, the integrated touch sensitive display ofthe mobile device may be a touch screen. A keyboard may be presented asthe digital input device. The keyboard displayed on the integrated touchsensitive display may be used to operate the mobile device. Theembodiments, however, are not limited to this example.

In an embodiment, multimedia content may be presented 515 to theexternal display of the mobile device in response to the operation ofthe mobile device through the digital input device. The multimediacontent may be an application executed, or running on, the mobiledevice. As discussed above, multimedia content may include, but is notlimited to, text, audio, video and images.

In an embodiment, the multimedia content may be presented on theintegrated touch sensitive display of the mobile device prior to themobile device being coupled to the external display.

By presenting the multimediacontent, the external display may become the primary display.

In an embodiment, the digital input device presented 510 on theintegrated touch sensitive display of the mobile device may be differentthan the media content presented 515 on the external display. In otherwords, rather than having both the integrated touch sensitive display onthe mobile device and the external display present the same multimediacontent, once the mobile device detects 505 that that the mobile deviceis coupled to an external display device, the integrated touch sensitivedisplay of the mobile device may present 510 a digital input device usedto operate the mobile device.

In an embodiment, the mobile device may detect 505 multiple externaldisplays coupled to the mobile device. In an embodiment, one or more ofthe external displays may present 515 the multimedia content in responseto operation of the mobile device through the digital input device. Forexample, the external display may be a monitor and multiple monitors maypresent 515 the multimedia content. In an embodiment, one or moreexternal displays may present 515 the same multimedia contentsimultaneously. For example, in a large ballroom, users may view variousscreens presenting 515 the same content, such as a movie.

FIG. 6 illustrates an embodiment of a second exemplary logic flow. Logicflow 600 may be representative of the operations executed by one or moreembodiments described herein. It should be noted that the methodsdescribed herein do not have to be executed in the order described, orin any particular order.

In an embodiment, a user may provide the information received 615 by themobile device about a digital input device by selecting a digital inputdevice. For example, a user may touch a certain place on the integratedtouch sensitive display which may cause the integrated touch sensitivedisplay to display various digital input devices. In an embodiment, theintegrated touch sensitive display may present a set, list and/or groupof digital input devices. In an embodiment, in addition to the set, listor group of one or more digital input devices, the integrated touchsensitive display may also list an option of displaying all or a portionof the multimedia content.

In an embodiment, a user may provide the information received 615 by themobile device by simply touching the integrated touch sensitive display.In an embodiment, the user may touch the integrated touch sensitivedisplay of the mobile device with his/her finger to make a selectionfrom a group, list and/or set. In an embodiment, the user may use astylus or virtual pen to make a selection. The examples are not limitedto the embodiments described.

In an embodiment, the mobile device may receive 615 information about adigital input device by receiving information that an external physicaldevice was added to the mobile system. As a result of an added externalphysical device, the integrated touch sensitive display on the mobilesystem may present a digital input device which provides a more detailedversion of a part of the external display screen. Alternatively and orin addition, as a result of an added external physical device, theintegrated touch sensitive display on the mobile system may present adifferent digital input device. In an embodiment, the digital inputdevice may complement the external physical device. For example, when akeyboard is coupled to a mobile device, the integrated touch sensitivedisplay may present a mouse.
